Climate Ready Estuaries
• Program through US Environmental Protection Agency
to work with National Estuary Programs and coastal
management community to:
1. Assess climate change vulnerabilities
2. Develop and implement adaptation strategies
3. Engage and educate stakeholders
Publications
Gulf Coast Community Handbook
• Identify adaptation strategies that incorporate
resiliency to climate change as a component of
habitat restoration and protection plans
• Focus on specific case studies from the Gulf region
• Guidebook for other coastal communities that
provides concrete examples of how to improve
habitat resiliency along the Gulf coast

Sea Level Rise
• Local measurements (St. Pete
Pier) document ~ 1”/decade
• Rate expected to increase
• Communities can use
scenarios based on the
“tolerance of risk”

Storm Impacts and Extreme Weather
• Sea level rise may increase
intensity of extreme weather
events
• Major flooding more common
• Barrier islands vulnerable
Source: Tom McKenzie, unknown
Changes in precipitation and temperature
• Warmer air temperatures
will impact precipitation
patterns and intensity
• Greater variability
predicted

Impacts to Flora and Fauna
• Examples of habitat migration or squeeze
• Changes in habitat ranges
Ocean Acidification
• pH decrease of 0.1 =
25% increase in acidity
• Threatens marine creatures
– Coral reefs
– Shellfish
– Algae
Source: University of Queensland, IPCC 2007
Additional Gulf of Mexico Impacts
• Land subsidence could
exacerbate sea level rise
– Oil and gas extraction
– Pumping of groundwater
• Significant wetland losses
– Louisiana loses a football fieldsized wetland every hour

Case Studies
• Highlight activities at Gulf Coast NEPs and NERRs
• Examples of collaborative projects as well as individual
initiatives

Step-by-Step Recommendations
• Assess current vulnerabilities
• Map areas that may become
inundated
• Identify habitats for protection
and preservation
• Prioritize strategies that
incorporate environmental
benefits
• Engage business community
• Develop post-disaster recovery
plans
